Application filed March 21, 1910, Serial No.

a citizen; ofthe United Statesresiding at -in common p Newport News. in

tain new and useful'lmprovements in Pins,

of. which the following is a specification,'ref'-" erence being had to This invention relates to improvements and more particularly ms, means for. preventing such pins from slipping out of the fabric orother' material in which they are placed; f

The object of the invention is to, provide a pin of this character having its body formed with a spirally twisted portion and with flatiportions at pin will be effectively prethearticle or object 'in which it placed. The above object of the invention is obaccompan tainedin the construction illustrated" in the 1 ing drawings in which:, s Figure is an enlarged side view of a'pin embodying my improvements; Fig. 2 is a similar view-lookin at the in from a plane at right angles to t at of ig. l; and Figs.

3, 4; and 5, are enlarged cross sectional views .nd 5-5 n Fig.1.

Referring more particularly to the drawings 1 denotes the body of my improved taken. respectively on' the lines 3-3, 4-4

" pin, which bodyis formed; from a piece of 'cylindricalwire having a circular cross sec At one'end of the pin body t onal shape. is formed the usual circular head 2 while its other end is tapered longitudinally -to'form the usual point 3.

In constructing the pin the intermediate. portion of the body 1 1s flattened so that it the county of Warwick and State of Virginia, have invented cerp the ends of the twisted per-1 tion, whereby'the vented from'worklng loose and retained in has two opposing broad flat faces and two as will be noted on reference to fiat edg'es Fig. 5. The central portion of the flattened partof the pin is then twisted spirally two or more times to form a reduced spirally twisted'part land enlarged flattened por tions 5 above and below the part 4. In twisting the fiattened portion of the pin the twists are made sufiiciently close to render the twisted portion of less diameter than the width of the untwisted portions 5, w ich "latter are thereby left of greater widththan the twisted intermediatetportion for the purpose of preventing the pin from working out of the cloth or other article in which it is inserted.

Having thus described is claimed is: 4

The herein described pin"co1nprising a cylindrical end portion haying a head; a

tapered poi'nt,.-and. a flattened intermediate portion between the said cylindrical end portion and said point, the end portions of said flattened intermediate portion" adjacent the the invention, what cylindrical'portionand point of the pin belng straight and in line with each other, and the-central portion of said flattened intermediate portion being spirally twisted and ofia diameter somewhat? less than the width of the straight ends'of saidintermediate flattened portion and enabling said straight ends of said flattened intermediate portion to prevent the pin from working out of an article in which it may be inserted.

In testimony whereof I hereunto afiix my signature in the presence of two witnesses.
